Rail vs. ETT

Category ETT TR Unit Factor Comment

Cost
Guideway cost per km $1.25 $17 $M/km 13.6 Use of higher cost material for ETT still produces big cost savings
Guideway cost per km / capacity 7 580.2 ($/km)/(p/hr) 80.2 Much better material utilization for ETT=huge reserve capacity for future growth
Guideway maintenance 0.12 0.53 cents/seat-km 4.4 Cost savings not as large due to maintenance of vacuum equipment
Station and Switch Cost 7.3 175 $millions 24 From China cost estimate reports
Station Capacity 700 14400 person/hr 20.6 12 trains per hour for TR (1200seats each)
Station Cost / capacity $10,429 $12,153 $/person/hr 1.2 ETT station cost advantage not as significant as other savings, ETT stations will be used closer to capacity due to 20 times better granularity of capacity
Vehicle cost per seat $4,700 $61,000 $/seat 13 Use of small vehicle size pays off big - much lower tooling and production cost
Vehicle maintenance 0.07 0.27 cents/seat-km 3.9 Cost savings not as large due to maintenance of life support equipment

Distance to stop 1.13 10.4 km 9.2  
External Sound Level 20 90 dB 128 times louder
Ice thickness buildup limit n/a 5 mm    
Kinetic Energy 1.45 329 kW-h 226.9  
Life-support Recharge / seat 50 N/A Wh/seat   ETT uses well proven technology developed for submarine and spacecraft
Magnetic field 1 to 1000 1 microTesla 1,000.00 Depends on maglev tech used by ETT
Maximum Grade 30 10 % 3  
Maximum power required 1 12 MW 12 Big cost savings for ETT
Min suspension gap 6 10 mm 1.7  
Minimum Curve radius at 200km/h 312 1000 m 3.2  
Minimum Curve radius at 300km/h 705 2250 m 3.2  
Minimum Curve radius at 400km/h 1250 4000 m 3.2  
Minimum Curve radius at 500km/h 1950 6200 m 3.2  
Operating Speed used to compare 500 500 km/h 1 Design speed fixed for comparison
Passenger capacity 172,800 29,300 persons/hour 5.9 Uses 1200 person capacity trains for TR on 147 sec intervals
Pumping Energy /seat / km 0.72 N/A Wh/seat/km   this is for a use of 25000 passengers per day - this number goes down for higher USA, and up for lower use.
running resistance per seat 1.05 200 Newton 190.5 The huge benefit of resistance elimination!
Safe Headway 0.125 147 seconds 1,176.00 For ETT determined by minimum capsule spacing and speed
Specific Energy Consumption 0.98 52 Wh/seat-km 53.1 TR is for 400km speed - number for 500 not available
Specific KE per seat 0.242 1.79 kW-h/seat 7.4  
Switch cycle time 0 30 seconds   No switch limits for vehicle frequency
Switching Speed 500 200 km/h 2.5 Full speed switching allows high vehicle frequency for ETT
Time to stop 20 147 seconds 7.4 means ETT can maintain speed longer for faster trip time
Time to top speed 20 256 seconds 12.8 ETT passengers seated and restrained - like in a car
Top Speed Potential 6000 600 km/h 10
